Grow the world's biggest Gigantomo Tomato and win up to £3,000

Gardeners lucky enough to get hold of 'Gigantomo'® plants or seeds in 2017 can take the fruits of their harvest to the Jubilee Sailing Trust Autumn Pumpkin Festival (14th October 2017) and take part in the National Gigantomo® Championships. Thompson & Morgan is offering a top prize of £250 for the heaviest fruit, with a further £3,000 jackpot up for grabs if it also breaks the world record at the time of the show* (currently 7lb 12oz).

'Gigantomo'® can reach over 6ft tall, producing fruits up to 10 inches wide and 3lbs in weight, which can be harvested from mid-summer. It is available as both seeds and plants. The new disease-resistant variety is the result of almost two decades of research and development by breeders in the UK and the US. Simon Crawford, one of the UK's leading plant breeders, was called in five years ago to finish the work of late American grower Paul Thomas, who spent 15 years trying to breed the huge tomato.

The Jubilee Sailing Trust Autumn Pumpkin Festival is staged at Royal Victoria County Park and hosts the UK Giant Pumpkin Championship.
